I got a look at the demo a few years back and agree with Capt Claret, there is not a lot of room for baggage or freight. If you have anything more than 85% load factor, you won't get any freight on.
The aircraft also suffers at high temps and short runways. It's really only suited for legs between 400-500 miles and runways greater than 1700m.
However it is a very nice aircraft up front and in the cabin.
